Keisuke's cousin, Takaya, lost three years of memories due to an accident. Seeking a trigger to regain his memories, Takaya wanted to stay at Keisuke's house for a few days, where he often came to play. Unfortunately, Keisuke was away on business, but Keisuke's wife, Miho, who knew Takaya well and was concerned about the aftereffects of the accident, welcomed him gladly. As Takaya spent time with Miho, fragments of his memories began to resurface…and he remembered that he had once proposed to Miho.
